2 Claims. (Cl. 106-199) The present invention relates generally to a plastic sealing composition for filling and sealing the cracks and joints between wooden members, which may be subjected to wide variations of temperature, and to relative mechanical movement. More particularly, the composition may be advantageously employed to fill the cracks and joints in wood floors.

My invention contemplates an economical, easily compounded composition which may be readily applied to the cracks and joints commonly found in wood floors, as included in dwellings of conventional construction, and which will retain a considerable degree of plasticity, but without undue fluidity, over long time periods, under a wide range of atmospheric conditions internally of a dwelling, and without cracking, or separating from the cracks and joints, even under transient pressures applied to the floor by persons walking thereon, movement of furniture supported thereon, and the like.

I have found a mixture in the proportions 1 lb. by weight of parafiin to 6 oz. by volume of paraflin oil to provide a suitable and preferred base material for my purposes, provided there is added to the base material about 6 oz. by weight of wood flour, or fine sawdust, and a small percentage, not to exceed 1% of common soap and borax. Colouring matter may be added as required, from aesthetic considerations. The quantity of wood flour employed may vary rather widely, say from 4 oz. to 10 oz. and the proportions of paraffin and paraiiin oil may vary by about 20% without adverse efiects, and to provide a usable range of plasticities in the finished product.

In preparing the composition the paraifin is raised to its boiling point. The parafiin oil is heated to its boiling point and the wood flour added. The boiling paraffin, and the oil and flour mixture are then combined and the resulting mixture brought to a boil. The soap and borax are then added, and the colouring matter, if desired, and the entire mixture slowly boiled until there results a compound of putty-like or plastic consistency. The compound is then molded into sticks, or to any other desired form.

When the finished product is applied to fill cracks or joints in floors, or the like, it is found that the material of the composition is suflicient- 1y plastic to fill readily and completely, and remains sufiiciently plastic, so that the relative motion of the wood members composing the floor, either in response to shear or to stress or strain, and whether caused by temperature variations, or other atmospheric variations, or by walking on the floor or moving heavy objects thereover, does not dislodge or crack the filler, or separate same from the wood.

The following example illustrates a composition within the range of proportions given, and which have proven satisfactory under actual use conditions:

Paraffin l3 oz.-19 oz. by weight Parafiin oil 4 oz.-7 oz. by volume Wood flour 4 oz.-10 oz. by weight Soap-borax of each not to exceed 1% of total composition.

What I claim is:

1. A plastic sealing composition consisting essentially of a mixture of paraffin, parafiin oil, wood flour, soap and borax, the composition having a plastic consistency, and wherein the ingredients have the following proportions:

(1) Paraflin, 13-19 parts by weight (2) Paraffin oil, 5-7 parts by volume (3) Wood flour, 4-10 parts by weight (4) Soap and borax in equal amounts, not to exceed 1% of the composition by weight.
